YARN-RECLAIMING MACHINE.

Specification of Letters Patent.

Patented May 6, 1919.

Application filed September 4, 1917. Serial No. 189,548.

To all whom it may concern Be it known that I, HARRY E. FIsH, a citi Zenof the United States, and a resident of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Yarn-Reclaiming Machines, of which the following is a specification,reference being had to the accompanying drawings.

It is often desirable in a garment manufactory to unravel a knittedgarment or piece of fabric because of imperfections in the work, orotherwise, and reuse the yarn or threads thereof for another piece ofwork. Such articles are frequently formed. of two threads that in theunraveling are removed together and for economic and other reasons it isof great advantage to have such two threads separated and separatelywound for future use, this being particularly true when such two threadsare of different material and of different values, as for example wooland mercerized cotton which frequently are combined in a knitted garmentor other article. 7

It is the leading object of my invention to provide a machine that willtake two such threads as they are unraveled from the garment or piece offabric and wind them separately, and simultaneously and evenly uponspools so that the threads can be taken to a knitting machine and againused in the customary manner. Further objects of the invention are toprovide automatic means for imparting a differential speed to the twospools upon which the threads are wound so that the pull upon the twothreads will be substantially uniform notwithstanding that one spool mayhave a greater quantityof thread or heavier thread wound upon it thanthe other spool; to provide means for auto matically stopping themachine when either of the spools hasv had the required amount of threadwound upon it; to provide means for so stopping the machine in the eventthat either or both of the threads break during the winding operation;to provide improved means for removably securing in place the rotatablespools, and also adjusting the frictional braking thereof so that onespool may slacken speed under certain conditions; and to improvegenerally machines for reclaiming yarns or threads from manufacturedfabrics. I attain these objects by the mechanism and combination ofparts illustrated in the drawings accompanying and forming a part ofthis specification. That which I believe to be new will be set forth inthe claims.

In the drawings:

Referring to the several figures of the drawings in which correspondingparts are indicated like reference characters:

15 indicates the base of the machine from which rise suitable framemembers that constitute the supports for the various operating parts ofthe mechanism. Adjacent to the rear edge of the base are shown three ofsuch supporting members indicated respectively by 16-17-48, and at theupper ends of these members is journaled a shaft 19. On this shaft. isloosely mounted a pulley 20, said pulley being movable longitudinally ofthe shaft by means of a bent shifting lever 21 pivoted at 9.2 to thestand ard 16,-the upper end of such lever being forked and engaging agrooved hub 23 which is formed with or made fast to the pulley 22. Theface of the pulley 20 opposite the grooved hub is provided with anannular series of friction studs 24 adapted to frictionally engage theface of another pulley :25 that is fast upon said shaft 19, the twopulleys thus constituting a clutch. 26 indicates a cone pulley fast onthe shaft 19, and 27 indicates a similar cone pulley made fast on acountershaft 28 journaled in bearings in the standards l7l8, this secondpulley lying directly below the firstnamed. pulley. At their smallerends they are provided with grooved pulleys 2930 respectively over whichruns an endless belt 31 so that the two pulleys are always driven at thesame speed. Adjacent to the front edge of the base 15 rise two framepieces or standards 3233 respectively which are provided near theirupper ends with suitable bearings in which is mounted a shaft 34 uponwhich is fixedly secured a cone. pulley 35. Also mounted in bearingscarried by these standards 3233 and directly below the bearings for theshaft 3-1 is another shaft indicated by 36. Upon this shaft 36 issecured a cone pulley 37 which lies directly beneath the cone pulley 35.The cone pulleys 35 and 37 are slightly smaller than the rear conepulleys 26 and 27, but are arranged respectively in substantially thesame horizontal planes as those last named pulleys, but it will be notedthat they are reversely arranged from the arrangement of the rearpulleys,that is the larger end of each cone pulley 3537 is toward adifferent side of the machine than are the larger ends of the rear conepulleys. 38 indicates an endless belt connecting the rear cone pulley 26and the front cone pulley 35, and 39 indicates an endless belt that inlike manner connects the rear cone pulley 27 and the front cone pulley37. It will, therefore, be evident that all four cone pulleys must bedriven when the shaft 19 is driven by reason of the engagement of thepulley members 20 and 25. 40 i1 indicate two spools adapted to berotated for the purpose of having threads wound upon them. The spoolsare in axial alinement with the shafts 34 and 36 respectively and arerotated as hereinafter described through such shafts. Each spool isconstructed and arranged as shown in the sectional view, Fig. 5, whereinit will be seen that the inner end of the spool L0 is recessed toreceive the reduced end of its bearing shaft 34-. Such reduced end ofthe shaft has secured upon it an annular head 42 which carries afriction band 43 of any suitable material against which the end of thespool bears. The outer end of the spool is rotatably mounted upon ashort stud 44 which has an annular plate 45 at a short distance from itsend to'limit the degree which the stud may enter the spool. The stud isseated in a chambered head 46 that is located in a sleeve 47 passingthrough the upper end of an upright standard 53. The stud -14: isretained in place in any suitable manner, as for example by a screw thatmay be passed through such head and project into a small annular channell8. as indicates a ball bearing interposed between the end of the stud44 and the end of the chamber in the head 46. 50 indicates a screw pluginserted in the outer end of the sleeve 47, and through this screw plugextends a long rod 51 that is formed with or connected to the chamberedhead 46. 53 indicates a light coiled spring around the rod 51 andbearing at its ends against. the chambered head 46 and the screw plug50. It will be evident that by varying the extent to which the screwplug is inserted in the sleeve 4-7, the endwise pressure on the spoolmay be "aried as required for proper winding results.

The thread-winding guiding devices by which the threads are directed tothe respective spools 40t1 and moved from end to end of such spools sothat the winding will be performed properly embrace the followinginstrumentalities: The pulley 25, through the endless belt 5%, drives apulley 55 that is fast on a shaft 56 in alinementv with the shaft 36.Such shaft is supported at its inner end in a bearing that is acontinuation of the bearing of said shaft 36 and at its outer end issupported in bearings formed with the framework of a housing 57 thatincloses a worm 58 fast on said shaft. This worm (see Fig. 9) engages aworm gear 59 fast on a. shaft, 60 that is journaled in bearings formedwith the housing of such worm gear. Such housing is indicattd by 61, andmay well. be formed with the housing member 57 that incloses the worm.On the shaft 60 is fixedly secured a pinion 62 that is in mesh with agear 63 journaled upon a short shaft 64-. Upon the end of this shaft 64that projects from the housing 61 is aflixcd a cam 65. 66 indicates anopen frame, the side arms of which embrace the cam, as shown in Fig. 1,and fit over the shaft on which said cam is mounted. In the forward. endof this frame is journaled a roller 66 against which the perimeter ofthe cam is in constant engagement. 67 indicates a connecting rodextending from the frame 66 toward the center of the machine where it isadjustably connected, in a manner about to be des' ribed, to an uprightlever 68 that is pivoted at 69 to a portion of the supporting frameworkof the machine. 70 i dicates av reciprocating bar adjustably onncctd tothe le er 68 near the upper end of such lever. -This bar is slidinglysupported it: two

fixed guides 71. One end of this bar 70, it will be noted, comesopposite the space between the two spools 10-41 and at that end itsupports a short vertical rod 72 in the ends of which are eyes arrangedto receive respectively the two threads that are to be wound upon thespools. 74 indicates a strong coiled spring secured at one end to theframework and at its other end to the lower end of the upright lever 68.Such spring tends, of course, to force the connect ing rod 67 toward thecam 65, and thus in sures a firm contact between the perimeter of saidcam and the roller 66 It is important, of course, to have thereciprocation of the bar 70 of just sufficient extent to insure theguide eyes 73 being carried from end to end of the two spools so as tocause the winding of the thread over the entire length of the spools,but as such spools may vary in length, it is necessary to provide meansfor lengthening or shortening the effective movement of the uprightlever 68 that carries the reciprocating bar. This I accomplish byproviding such lever just above its pivot 69 with a slot 75 and pass-'ing therethrough. a bolt 76, upon a projecting and enlarged end ofwhich the connecting rod 67 is journaled (see Fig. 10). This connectingrod fits between the head of the bolt and a washer 77 that is fittedupon the reduced part of the bolt and lies against the face of the lever68. On the opposite end of the bolt is screwed a nut 78 between whichnut and the face of the lever is interposed a washer 79. From this itwill be seen that the nut can be tightened up so as to hold the bolt inany adjusted position in the slot 75 without bringing to bear anypressure upon the connecting rod 67 that would prevent the free turningof such rod on the bolt. It is, of course, evident that according to theposition to which the bolt is adjusted in the slot will depend the degree of movement of the lever 68 on 1ts pivot, and consequently willregulate the reciprocating movement of the threadsguiding rod 72. Theupper end portion of the lever 68 is also slotted as at 80, and throughsuch slot passes a stud 81, the head of which bridges the slot 80 andbears against the face of the lever 68. This stud at its rear endcarries a block 82 through which passes the reciprocating bar 70, saidbar being locked to the block by a set screw 83. The block is preferablychanneled so that its side ledges lie along the side of the edgesof thelever 68 as shown. By loosening the set screw 83 the bar 72 can be advjusted so as to bring its outer end that carries the threads-guiding rodexactly in the right relation with respect to the spools that are to beemployed. and when such. correct position is attained, the bar 70 willbe locked on its block by the set screw 83.

The provision of the slot 80 allows the required up and down movement ofthe pivot 81 relative to the lever as such lever 68 is rocked on itspivot 69. I

In rear of each spool is a roller that constantly bears against thethread that is being wound upon the spool, and as the thread winds up inincreasing layers, such roller moves back and during such movementperforms two functions,-namely it automatically moves the driving beltlengthwise of the front and rear pairs of cOne pulleys so as to vegradually slow down the speed of the spoo and thereby insure a steadyand even pull on the thread being wound there on; such receding motionof the roller also sets in motion the means by which the machine isbrought to a stop when the particular spool that such roller is workingin conjunction with is fully wound. The roller used in connection withthe uppermost spool-that is the spool 40-is indicated by 84. It is journaled in a yoke 85 that is pivoted at 86 to an arm 87 that is pivotedat 88 to one side of a bracket 89 bolted to the framework. This arm 87has a rearward extension 90'. This portion 90, as shown, is

depressed so as to lie slightly below the plane occupied by the mainportion of the curved arm 87, and the upper face of such portion 90 isbeveled or inclined to form a cam surface 91. On this cam surface 91rests the free end of a short lever 92 which lever is pivoted at 93 to afixed portion of the framework. Midway between the ends of the shortlever 92 is pivotally attached :1 depending bar 94: that passes througha guiding member 95 attached to the framework, and at its lower endcomes opposite a ledge 96 that is formed with and projects up-.

wardly from an arm 97. This arm 97 has a hub portion 98 that isjournaled on a vertical pin 99. 100 indicates a coiled spring around andsecured to said pin 99 and also secured to the hub 98 and acting toswing the arm 97 when permitted to do so by the raising of the bar 94sufliciently to clear the ledge 96. The arm 97 is connected by a link101 to a crank 102 fast on a rock-shaft 103 that extends alongat oneside of the machine and near the base thereof. This rock-shaft 103 issuitably journaled in short standards, one of which is shown andindicated by 104, and near the upper end of such short standards isjournaled another rock-shaft 105. The two rock-shafts 103 and 105 arenormally connected together through the instrumentality of a hand lever106 that is made fast to the forward end of the shaft 105 and has alatching engagement, as best shown in Fig. 8, with an arm 107 fixedlysecured upon the forward end of said shaft 103. The latching connectionof the hand lever 106 with this arm 107 is efl'ected by means of a pin108 engaging a notch in one end of the arm 107. Such engagement isintentionally of a character that can be broken with comparativelylittle difiiculty when required, but which will be firm enough to holdthe parts in normal position. The turning of the rock-shaft 103 by theswinging of the short lever 97 in the manner described will, of course,rock the arm 107 so as to break the latching engagement referred to, andthereupon the other rock-shaft will also be rocked and such rocking orturning will be compelled by the endwise pressure of alongitudinally-movable rod 109. This rod 109 has at its outer end, asbest seen in Fig. 2, a fiat head 110 with which a small roller 111contacts, such roller being journaled in the end of a crank 112 fast onsaid rockshaft 105, and as this crank 112 stands at a little upwardinclination any endwise movement of the rod 109 will throw the outer endof said crank upward and cause a turning of the rock-shaft 105 withwhich it is connected. Such turning may also be assisted by a coiledspring 113 (see Fig. 7) encircling the rock-shaft and connected to itand also to the short standard 104. but ordinarily, it is believed, theturning of the shaft 105 can be accomplished without the use of suchspring. The endwise movement of the rod 109 is effected by means of acoiled spring 114 that is interposed between a collar 115 that is faston said'rod and the lower end of the bent shifting lever 21 that has asuitable connection at its lower end with the rod 109,.such connectionbeing preferably a pin and-slot connection as illustrated. The effect ofsuch endwise moving of the rod 109 is to turn the shifting lever 21 uponits pivot 22, and thereby, of course, draw the driving pulley 20 out offrictional clutching engagement with the pulley 25, and that necessarilystops the machine. It will be noticed by reference to Fig. 2 that thedriving belt indicated by 116, that leads from any suitable motor overthe pulley 20, is conducted to that pulley 20 on a slight incline, andsuch inclination would aid in the shifting of the pulley 20 as the drivebelt would necessarily tend to run in a straight line.

From what has been said, it will be evident that as the layers of threadmultiply on the spool 40, the roller 84 will gradually be pushed backand cause a turning of the curved arm with which it is pivotallyconnected, and as this movement takes place the short lever 92 will verygradually be lifted .by riding up the inclined or cam surface 91;

upon the required amount of yarn or thread being wound upon such spoolto fill it, the

lever 92 will have been raised to the highest point of the cam surface,which will draw up the bar 9% sufficiently to disengage it from theledge 96, whereupon the movement of the other parts that operate to stopthe machine will occur as described. Behind the lower spool is lo"a'teda duplicate set of devices such as described in connection with theupper spool, and they are, therefore, correspondingly numbered. Theshort pivoted lever 92 of this lower set of devices is also pivotallyattached to the vertically sliding bar 9%, and therefore, it is evidentthat through that lower one of the two lovers 92 said bar may be movedupwardly to exactly the same extent and for the same purpose as in thecase of the upper pivoted lever 92.

Now it is evident that if both spools -l-0-l1 have threads wound uponthem simultaneously to the same extent and both threads are of acharacter to increase the diameter of the spools equally. then the twosets of mechanism will move exactly alike and each of the levers willexert an equal lifting effect upon the bar 9% and both spools will becompletely wound when the. machine is automatically stopped in themanner described. But it may well happen that owing to the differentcharacter of threads being wound upon the two spools or be-auee the.machine may be started with one spool partially filled and the otherempty. that the two sets of mechanism will not, of course, move exactlythe same. F or example, we will suppose that when the machine is startedthat the upper spool -10 has a considerable quantity of thread woundupon it, whereas the lower spool i1 is empty. The result will be, ofcourse, that the winding of the upper spool will be finished by the timethat the lower spool is only partially wound. It is just as necessary,of course. that the machine be automatically stopped when one of thespools is completely wound as in the case where the winding is finishedon both spools at the same time. In the case supposed, the devicescontrolled by the barkward movement of the roller S-l that contacts withthe upper spool will at all times be advanced farther in theirmoven'ients than the corresponding devices of the lower set, and thelifting will all be done through the medium of the upper pivoted leverowing to the fact that the lower lever 92 will be held out of contactwith its cam face 91. It will thus be seen that the two mechanisms mayunitedly lift the bar 94 out of holding engagement with thespring-pressed pivoted. lever 97 or either one of them may perform thatoperation, depending upon the quantity of thread on the spools.

It is highly desirable that an even and regular pull be exerted on thethreads as they are drawn to and upon the respective spools 4l0-41, andwith the machine being driven at a uniform rate of speed during thewinding operation this would not be possible unless some provision weremade for so drawing the threads, because of the fact that as the layersof thread multiply on the spools, the surface speed of the thread on thespools increases. To attain the desired even pull I have provided inconnection with each of the mechanisms controlled by the gradualbackward movement of the rollers 84 certain means for automaticallyefi'ecting a lateral shifting of the belts 38 that extend between thetwo sets of rear and front cone pulleys, and as these devices areexactly the same in connection with each set of mechanism they aremarked with the same reference numerals. As best shown in Fig. 1, itwill be seen that to that end of the bracket 89 opposite the point ofattachment of the curved arm 87-90 is pivoted at 117 an arm 118 whichcarries at its rear free end an upright roller119. 120 indicates a linkpivotally connected at 121 to the arm 118 and pivoted at 122 to theshort arm of the curved member 8790. The upright roller 119 lies incontact with the edge of the ad jacent drive belt and as the spoolroller 84 and its attached curved arm moves slowly back, such curvedarm, turning on its pivot 88, will cause the upright roller 119 to movesuch belt along its cone pulleys-moving it toward the smaller end of therear cone and the larger end of the front cone, and hence regulating thespeed of the shaft carrying the spool so as to maintain the desired evenpull on the thread being wound thereon. A corresponding belt shiftingdevice is pro .vided in connection with the mechanism in rear of theother spool whereby in like manner the position of the other belt on thetwo Other cones is regulated. Each belt shifting mechanism is entirelyindependent of the other, as is the case with the machine stoppingmechanisms with which they are respectively connected.

In addition to providing means for automatically stopping the operationof the ma chine when one or both of the spools is or are fully wound, itis of very considerable importance to have the machine automaticallystopped in the event of the breaking of either or both ofthe threadsthat are being led to the spools. I have provided means for theaccomplishment of this object which I will now describe. At the front ofthe machine rise two frame members or standards 123-12 1. These memberscarry two sets of cooperating thread engaging devices, one set for usein connection with the thread led to the spool 40 and the other inconnection with the thread led to the spool 11. The construction andoperation of each set of devices is exactly the same, and therefore,they are indicated by the same numerals and a description of theconstruction and operation of one set will suffice for the other. 125indicates a plurality of wires extending horizontally from the innerface of the up right 123. The end wires of this set are coiled uponthemselves to provlde guide loops 126 the intermediate wires being overthe spaces between the set of wires 125. 7

These wires 127 are carried by a head 128,

such head being integral with an arm 129 that fixedly secured to a shortshaft 130 journaled in a bearing that is formed with a bracket 131projecting from the inner face of the upright 12 1'. On the opposite endof said short shaft is fixedly secured a bellcrank lever 132 and to theoutwardly-extending member of this bell-crank lever is attached one endof a light coiled spring 133, the other end of which is attached to aten sion regulating screw 131 that passes through a bracket 135 on theupright 124. The other end of this bell-crank lever has pivotallyattached to it the upper end of a link 136.

This link passes through an opening in a guide bracket 137, and thelower end of such link is immediately over and in close proximity to thelong end of the arm 107 that is fast on the rock shaft 103. In operationthe thread to be wound upon one of the spools will be passed between thetwo sets of wires 125 127, and through the loops 126 on the end wires125, from which it will pass through the proper eye 73 of the rod 72 andthence to the proper spool. The taut thread in its passage between thewires will exert a suificient upward pressure on the set of wires 127 tokeep those wires in a substantially horizontal position, this upwardpressure being. as will be understood, against the action of the lightcoiled spring 133. The loops 126 on the lower set of wires hold thethread from rising and unduly raisin; the set of wires 127. If therunning thread should break, the upward movement on the set of wires 127would, of course. be released, as soon as the end of the thread passedbeyond the wire fingers, and immediately thereafter the coiled spring133 would turnthe bellcrank lever 132 to which it was attached, which inturn would cause a rocking of the shaft 130 and a swinging down-of thearm 129 that is also fast on the short shaft 130, the wires 127 passingdown between the wires 125. The swinging of the bell-crank lever 132would also force down the depending rod 136- connected therewith andcause it to strike the end of the arm 107 with sufficient force torelease the pin 108 from its engagement with the hand. lever 106. Therock-shaft 105 would thereupon be turned and the machine stopped throughthe movement of the parts 109, 21 and 20 as described in connection withthe stopping operation caused by the completion of the winding of thespool. As before explained there is a set of devices of the characterjust described employed in connection with each of the two threads-theonly difference between the two sets being that, necessarily, the rod136 carried by the lower bell-crank lever is shorter than the rodcarried by the other bell-crank lever. It, therefore, follows that uponthe breaking of either thread the machine will immediately be stopped inthe manner described.

Many changes in details of construction from that shown and describedmay be made Without departing from the spirit of my invention, andexcept as specifically claimed my claims are not to be construed aslimited to such details.

In a machine of the class described, the combination with twothread-receiving spools and means for rotating the same simul taneously,of mechanism for stopping the machine, such mechanism comprisingduplicate and independently-acting sets of members each set beingarranged in operative relation to one of the spools and having anelement in contact with the thread being wound upon that spool and alsocomprising a set of members to which both of the said duplicate andindependent sets are connected, whereby the machine will be stopped wheneither spool is wholly wound.

9. I11 a machine of the class described, the combination with twothread-receiving spools arranged in different horizontal planes andmeans for rotating them simultaneously, of mechanism for stopping themachine comprising two duplicate and independently acting sets ofmembers each set being arranged in operative relation to one of thespools and in contact with the thread being wound upon that spool andalso comprising a third set of elements arranged at a distance from saidtwo independentlyacting sets, and a depending bar connected with apivoted member of each of said independently-acting sets and in movablelocking engagement with the said third set.

10. In a machine of the class described, the combination with twothread-receiving spools arranged in different horizontal planes, andmeans for rotating them simultaneously, of mechanism for stopping themachine comprising two duplicate and independently acting sets ofmembers each set being arranged in operative relation to one of thespools and in contact with the thread being wound upon that spool andalso comprising a third set of elements arranged at a distance from saidtwo independently-acting sets, and a depending bar in movable lockingengagement with said third set and adapted to be raised by thesimultaneous action or the separate action of said two independently-acting sets.

11. In a thread-winding machine, the combination with a driveshaft and aclutch device thereon, of a second shaft, a cone pulley fast on eachshaft, an endless belt passing around said pulleys, a thread-receivingspool rotated by said second shaft, a device for gradually moving saidbelt along the pulleys as the winding operation progresses, means forautomatically shifting one of the clutch members on the drive-shaft forthe purpose of stop-ping the machine, and a movable device in constantengagement with the thread on the spool for simultaneously moving saidbelt-shifting device and said clutch-shifting means.

12. In a machine of the class described, the combination with twothread-receiving spools and means for rotating them simultaneously, ofmeans for gradually varying the speed of the spools independently assuccessive layers of thread are wound thereon, and means for stoppingthe rotation of both spools when the winding on either spool iscompleted.
